| Scientific title | A randomised controlled trial of VSL#3 for the prevention of endoscopic recurrence following surgery for Crohn's disease |
| Study objectives | To determine the efficacy of the probiotic VSL#3 in the prevention of Crohns disease development following surgical resection and re-anastomosis. |
| Ethics approval(s) | The Health Research Ethics Board (Biomedical Panel) of the University of Alberta, Edmonton, Alberta, gave approval on the 22nd June 2001 |
| Health condition(s) or problem(s) studied | Crohns Disease/Inflammatory Bowel Disease |
| Intervention | A randomised controlled trial of VSL#3 versus placebo Trial details received 12 Sept 2005 |
| Intervention type | Other |
| Primary outcome measure | To assess the efficacy of VSL#3 for the prevention of severe endoscopic recurrence (Rutgeerts Grade three or four) of Crohns disease, within 90 days of study treatment, in patients who have undergone an ileocolonic resection with small intestine to colonic anastomosis |
| Secondary outcome measures | 1. To assess the efficacy of VSL#3 to prevent all endoscopic recurrence of Crohns disease (Rutgeerts Grades one to four) within 90 days of study treatment 2. Determine the proportion of patients who require medical therapy for management of recurrent Crohns disease within 90 days of study treatment 3. To compare the time to severe endoscopic recurrence of Crohns disease (Rutgeerts endoscopic grade three or grade four) in subjects who receive immediate (within 30 days post resection) versus delayed (more than 90 days post resection) introduction of VSL#3 as maintenance therapy 4. To determine the proportion of patients who require medical therapy for management of their recurrent Crohns disease within 365 days of study treatment 5. To compare the treatments for overall Crohns disease activity as measured by the Crohns disease activity index (CDAI) 6. To compare the treatment for disease specific quality of life endpoints as measured by the inflammatory bowel disease questionnaire (IBDQ) 7. To assess the safety and tolerance of VSL#3 8. To determine: 8.1. The quantity and type of bacterial colonisation 8.2. Mucosal cytokine levels 8.3. Histologic injury 8.4. Mucosal metalloproteinase activity at the neo-terminal ileum and serum cytokine genotyping These studies will be conducted at a subset of participating centres in Canada. |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Adult |
| Sex | Both |
| Target number of participants | 120 |
| Key inclusion criteria | 1. Subjects who are 16 years of age or older 2. Have a diagnosis of Crohns disease of at least three months duration, prior to ileocolonic resection, and the diagnosis is confirmed by radiological studies or endoscopy with biopsy or surgical pathology 3. Resection of ileocolonic Crohns disease, with margins macroscopically free of disease, and small bowel to colonic anastomosis no more than 30 days prior to randomisation 4. Females of child-bearing potential (have not had tubal ligation, hysterectomy or other surgical procedure for sterilisation) must have a negative urine or serum pregnancy test within one week of entry into the study and agree to use an acceptable method for contraception throughout the trial. Acceptable methods of contraception include oral contraceptives, implantable contraceptives, injectable contraceptives, intrauterine device or barrier methods (diaphragm with spermicidal gel plus condoms, condoms with contraceptive sponges, condom plus intravaginal suppository). 5. Voluntarily able to provide informed written consent |
| Key exclusion criteria | 1. Use of other medications for the treatment of Crohns disease following surgical resection (perioperative steroids in tapering doses and antidiarrhoeal agents - codeine, loperamide, diphenoxylate or cholestyramine are acceptable) 2. Treatment with a tumour necrotising factor (TNF)-antagonist in the eight weeks prior to resection 3. Clinically significant Crohns disease elsewhere in the gastrointestinal tract 4. Clinically documented short bowel syndrome (greater than 100 cm of small bowel resected) 5. Serious underlying disease other than Crohns disease 6. Significantly impaired liver or renal function 7. History of cancer with less than two years in a documented disease-free state (other than resected cutaneous basal and squamous cell carcinoma and or in situ cervical cancer) 8. Patients with the following laboratory abnormalities: 8.1. White blood count less than 3 x 10^9/l 8.2. Lymphocyte count less than 0.5 x 10^9/l 8.3. Haemoglobin less than 80 g/dl 8.4. Platelet count less than 125 x 10^9/l or more than 800 x 10^9/l 8.5. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) more than 2.0 times the upper limit of normal 8.6. Alkaline phosphatase more than 2.0 times the upper limit of normal 8.7. Serum Creatinine more than 1.5 times the upper limit of normal 9. Patients using ethanol or consuming illicit drugs which, in the investigators opinion, may interfere with compliance with the study procedures 10. Patients with active psychiatric problems, which, in the investigators opinion, may interfere with compliance with the study procedures 11. Patients using concomitant investigational therapy 12. Patients who are unable to attend study visits or comply with study procedures |
